J. Neilson Barry took the "course distance and remarks down the KosKoskee River" recorded by William Clark on October 10, 1805, and plotted them out to trace the expedition's progress down what is now known as the Clearwater River on their journey westward.  See pages 256-258 of Volume 5 of The Journals of the Lewis & Clark Expedition (1988).
